For tumors that can be graded via FNCLCC (some cannot) all dedifferentiated (undifferentiated) sarcomas received 3 points for their cytodifferentiation score. —Histologic grading is the most important prognostic factor and the best indicator of metastatic risk in adult soft tissue sarcomas. [1] The AJCC follows the grading system of the French Federation of Cancer Centers Sarcoma Group (FNCLCC). In: Amin MB, Edge SB, Greene FL, et al.

The most commonly used systems are the French grading and the National Cancer Institute grading. The most widely used, and therefore validated, is the FNCLCC (Federation Nationale des Centres de Lutte Contre le Cancer) system. This system considers the degree of cellularity, cell and nuclear polymorphism, differentiation, the presence and amount of necrosis, haemorrhages, mitotic activity and growth pattern, but does not score the different parameters (12). FNCLCC grading is composed of three components: 1) cytodifferentiation score 2) score for mitotic rate 3)score for necrosis.
